Title: TV blurry
Post by: DemonBrew on October 23, 2005, 03:49:24 pm

My TV image is pretty blurry - can't read the fonts on the Windows98 desktop. It's very tough to read the games list in either AtomicFE or Mamewah. I'm guessing it's my setup, but looking for some suggestions:

Win98SE
GeForce 4 MX 4000 PCI card S-video out to
Radio Shack RF ModulatorVideo Component Adapter that goes to
25" TV with coax cable.

The TV ONLY has a coax input. No componant, no composite, no S-video. Nada. Zip.

Screen resolution is set up 640x480. Tried messing with the Nvidia display settings for TV, nothing makes any difference.

Any ideas?

S video made a world of difference on mine.  I think you will be very limited as to what you will be able to see clarity wise.

The TV ONLY has a coax input.

Rule of thumb: the more signals that get carried on a wire, the more interference (read: "fuzziness") you get.

On VGA/RGB you get 8 wires: Red, Green, Blue, R-Ground, G-Ground, B-Ground, Horizontal Sync, Vertial Sync.  1 signal per wire for the best "sharpness".

Go down the list and you get Component (Y+Sync, Pr, Pb), then S-Video (Chroma/Luma) then comopsite (everything in 1 cable).  Last on the list is coax.  All video and all audio on one cable.  The absolute worst image quality you can ever get.

If you want a better picture, you have no choice other than to get a new television/monitor.  There is just nothing you can do in your current situation to get a better picture.  Sorry.

That's what I figured. Especially if I'm shoving the signal through an RF Modulator.

Game play itself isn't half bad. I've got a post over in the software forum to see if I can tweak the front end to display larger fonts.

Thanks!

Switch Tv's... or bring a TV with S-VIDEO beside your arcade and see what the change is like.

Trust me. watch the world of difference!

Did you see if you could simply get an svid-RCA pigtail connector and avoid the modulator?  Lots of laptops come with the little 3" adapters, probably could find one to use somewhere (as long as the svideo connection on the pigtail isn't some proprietory one).

something like this:
